Quantum Foundation Combines Bitcoin and Ethereum to Create Qtum

Posted by in categories: bitcoin, cryptocurrencies, finance, quantum physics

Nice try; no faith it will succeed long term with QC.


Singapore-based Quantum Foundation announced that it is working on a new project called Qtum, which combines the technology of both bitcoin and ethereum to facilitate blockchain technology adoption for corporations. Qtum is an open-source blockchain project that aims to build smart contract functionalities that can be implemented at an enterprise level.

The initial financial backing of $1 million by several industry leaders is a testament to the validity of the technology that the Qtum project is creating but also demonstrates full faith in its team of developers. Early-stage angel investors in the project include ethereum co-founder Anthony Di Iorio, Fenbushi partner Bo Shen, and OKCoin CEO Star Xu, among others. The Qtum project also intends to launch its native cryptocurrency to support the project through a crowd sale to raise further funds.

China’s Quantum Communications Trailblazer declared Operational after Stellar Performance

Posted by in categories: cybercrime/malcode, quantum physics, satellites

Nice write up on the QC news about China’s QC satellite from late Wed.


China’s Quantum Science Satellite was declared operational this week after five months of in-orbit testing, now set for a busy two-year mission demonstrating hack-proof communications by means of entangled photons as a trailblazer for what is widely considered the communications technology of the future.

The Quantum Science Satellite, nicknamed Mozi, was launched into orbit on August 15, 2016 as the world’s first dedicated quantum communications testbed, embarking on an ambitious mission dedicated to validating the principles of quantum communications across vast distances of open space.

Bristol professor reveals quantum power behind new industrial revolution to world leaders at Davos

Posted by in categories: business, computing, quantum physics

As the world’s political and business leaders gathered at Davos, it fell to a professor from the University of Bristol to reveal to them the full implications of a ‘fourth industrial revolution’.

Professor Jeremy O’Brien, director of the Centre for Quantum Photonics at the University of Bristol, addressed some of the most powerful people in the world yesterday at the annual meeting of the World Economic Forum (WEF) in Davos, Switzerland – to tell them just how rapidly quantum computers could change the world.

Part of the European Research Council (ERC) Ideas Lab delegation, Professor O’Brien has been actively involved with the WEF over the past few years and recently took on the role of co-chair of the Global Future Council on Computing. Last year he presented a talk on working towards a quantum computer discussing the future of computing and how new fields of computer sciences are paving the way for the next digital revolution.

Violations of energy conservation in the early universe may explain dark energy

Posted by in categories: cosmology, quantum physics

(Phys.org)—Physicists have proposed that violations of energy conservation in the early universe, as predicted by certain modified theories of quantum mechanics and quantum gravity, may explain the cosmological constant problem, which is sometimes referred to as “the worst theoretical prediction in the history of physics.”

The physicists, Thibaut Josset and Alejandro Perez at the University of Aix-Marseille, France, and Daniel Sudarsky at the National Autonomous University of Mexico, have published a paper on their proposal in a recent issue Physical Review Letters.

“The main achievement of the work was the unexpected relation between two apparently very distinct issues, namely the accelerated expansion of the universe and microscopic physics,” Josset told Phys.org. “This offers a fresh look at the cosmological constant problem, which is still far from being solved.”

On-demand pain relief, triggered by light

Posted by in categories: biotech/medical, materials, quantum physics

It will be amazing how this advances with Quantum.


Once injected into the body, a new material can repeatedly release small bursts of local anesthetic when zapped by low-intensity, near-infrared light for one minute (Nano Lett. 2016, DOI: 10.1021/acs.nanolett.6b03588). The material’s developers, who have tested it in rats, say the on-demand system could make pain management safer and more effective, and give patients more control.

The PBR Theorem explained

Posted by in categories: particle physics, quantum physics

The PBR theorem is another theorem of quantum mechanics, which could go alongside Bell’s Theorem and the Kochen-Specker Theorem. I wrote this explanation in 2011, before the paper was officially published in Nature. Since then, it’s been recognized as a moderately important theorem, and it has been named after its three authors (Pusey, Barrett, and Rudolph). But at the time I didn’t really know whether it would become important.

There’s a new paper on arxiv called “The quantum state cannot be interpreted statistically “. It has a theorem which proves that, given a few basic assumptions, the quantum state (ie the wavefunction) must be real, rather than a merely statistical object. Nature has an article which mostly just harps on how “seismic” the paper is.

Nature (correction: the article’s author, not Nature itself) compares its importance to Bell’s Theorem, which is a very important result indeed from 1964. Bell’s theorem proved that if there were “hidden variables” underneath the quantum state, then entangled particles must be communicating with each other faster than light. I’ve explained Bell’s theorem in the past.

Physicists Say They’ve Manipulated ‘Pure Nothingness’ and Observed the Fallout

Posted by in categories: particle physics, quantum physics

According to quantum mechanics, a vacuum isn’t empty at all. It’s actually filled with quantum energy and particles that blink in and out of existence for a fleeting moment — strange signals that are known as quantum fluctuations.

For decades, there had only ever been indirect evidence of these fluctuations, but back in 2015, researchers claimed to have detected the theoretical fluctuations directly. And now the same team says they’ve gone a step further, having manipulated the vacuum itself, and detecting the changes in these strange signals in the void.

We’re entering the territory of high-level physics here, but what’s really important in this experiment is that, if these results are confirmed, the researchers might have just unlocked a way to observe, probe, and test the quantum realm without interfering with it.
